AI Technical Summary

Technical Problem

In low-temperature environments, the rubber damping components of electric compressors harden, leading to increased stiffness and reduced vibration isolation effect, making it difficult to maintain stable vibration reduction performance over a wide temperature range.

Method used

The metal leaf spring vibration damping unit uses multiple metal leaf spring components to generate bending deformation in different spatial directions, forming multi-directional elastic support, decoupling the translational and oscillating vibrations of the compressor, and constructing a multi-degree-of-freedom vibration system whose natural frequencies are concentrated within a preset frequency band.

Benefits of technology

It maintains stable and reliable vibration reduction performance over a wide temperature range, effectively absorbs and isolates compressor vibration, and improves vehicle operating comfort.

Abstract

The application relates to a compressor mounting structure, a design method of the compressor mounting structure and a vehicle. The compressor mounting structure comprises a plurality of metal plate spring damping units, each of which has a first connecting position and a second connecting position, the first connecting position being connected to a vehicle frame, and the second connecting position being connected to a compressor. According to the application, the metal plate spring damping unit is used as a substitute for a rubber damping element, is not sensitive to temperature changes, and thus overcomes the defects of traditional rubber damping elements, i.e. the stiffness is increased and the vibration isolation effect is reduced due to hardening at low temperatures. Meanwhile, the plurality of metal plate spring damping units can form a uniform and stable multidirectional elastic support, effectively absorb and isolate the vibration generated by the compressor in each direction, and inhibit the vibration transmission. Therefore, the compressor mounting structure can maintain the stability and reliability of the damping performance in a wide temperature range including a low temperature environment, and improve the comfort during the operation of the vehicle.
